Suggestions for best Dahon for a 100 mile Bike Tour

What would your suggestions be for the Dahon that would be best for doing 25-100 mile weekend rides? I'm not overly interested in high speed (Speed Pro)- but a bike that can do the distance with some speed . I have a Vitesse D7/HG for commuting in/around NYC. I'm extremely pleased with it - but need something that can handle the upcoming NYC Century Bike Tour. The specs for the MU P24 mentions 'centuries' (in it's list of 'perfect for') - so I assume it is a front runner for my purpose.

I'd be pleased to hear your views on this - and alternative suggestions. I'm planning to buy this week if possible so I can get into 'training' and get the feel of the bike before the event.

Assuming the centuries are relatively flat, then you may be fine with the Vitesse. What gear range does it have? I might be good to install a smaller cog at the back to get higher gearing for the faster speed; investing in some good tyres for such will also make a big diference. Make sure your handlebars, grips, saddle and pedals are good for it too. Dropping off as much excess weight as possible for long rides is a good idea too.

It's internal hub - 7 gear bike. I've made some changes to the original spec - swapping the seat for a Brooks Pro 'S'; replacing the handgrips with Brooks leather tape and replacing the pedals with MKS 'EZ'. I'm not sure this has added much to the original weight, if anything at all. I've also added the rear touring rack. I'm about to change the tires to something a little more forgiving (I'm tackling NYC streets for a daily commute).
